segmentation fault with python for closing the script file

I am getting the following segmentation fault with various repository versions (below from the current master f79438):

make check works, but the following does not:

$ dlvhex2 examples/python.hex --pythonplugin=./testsuite/plugin.py

In gdb this gives the following backtrace:

Program received signal SIGSEGV, Segmentation fault.
